I just Googled "female to male binders" and got all kinds of hits. Follow the hits and he will find explanations too on some of the sites. Amazon.com was the first listing. I don't know where he lives but lesbian bars tend to attract all kinds of people, including FtM trans people. Get in with a group of them and he will get all kinds of information. Also, even though we do not have many active FtM members here now, we used to have a very active core group when I fist started. I used to join their threads when I had something to add. There were a lot of very good discussions on HRT, voice, hair growth, binding, packing, SRS/GRS, penile implants, etc. The key point is to find a place where he can network and do just that. Once that door of contacts gets opened it is much easier to get good information and recommendations too. Tell him good luck and to join here so that he can do his own searches on his own time, and it will take some time.
